Molecular dynamics investigation of melting and phase transition behaviors of fcc Fe nanoparticles [PDF]
, 2011 铁纳米粒子在磁存储、生物医学、催化剂等领域有着广阔的应用前景。众所周知，块体铁在自然环境下呈现为体心立方结构（bcc），当温度高于1185K时，块体铁会相转变为面心立方结构（fcc）。Bcc结构的铁纳米粒子可以利用热分解或者电化学等方法得到。目前已有许多研究者从理论和实验上开展了bcc结构铁纳米粒子的研究。近年来，实验上人工合成了具有孪晶结构的fcc铁纳米粒子，但是理论上有关fcc结构铁纳米粒子的热稳定性的研究还十分少见。因此本文采用分子动力学方法对fcc铁纳米粒子的性质进行了计算模拟 ...

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, EarlyView.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

Theoretical studies of proteins, protein complex and antimicrobial peptides-membranes through molecular dynamics simulations [PDF]
, 2014 生物大分子的动力学特征对其结构和生物学功能均有重要影响。本文利用分子动力学模拟研究了四个不同类型的生物大分子。 类弹性蛋白多肽(ELPs)在室温下可溶，但当温度高于其相变温度(Tt)时沉淀析出，异于普通蛋白质。ELP-KV8F在NVT系综分子动力学模拟结果显示其在盐溶液中收缩更为剧烈，ELP-KV8F在水溶液中收缩程度最强的温度为375K，而在1MNaCl盐溶液中则为350K。在较低温度条件下，升高温度使ELP-KV8F分子收缩程度更剧烈，当温度升高到一定极限后这种变化趋势反转 ...

Policy &Internet, Volume 18, Issue 1, March 2026.ABSTRACT This article investigates how TikTok Shop reproduces the e‐commerce model of Douyin Shop against a backdrop of divergent regulatory challenges and geopolitical distrust. One of the strategic changes we observe in TikTok Shop is the shift of consumer goods suppliers from local merchants to China‐based sellers.

分子动力学研究He对钨Σ3{112}对称晶界拉伸性能的影响 [PDF]
, 2019 使用分子动力学方法计算模拟了Σ3{112}晶界上含有不同大小和浓度He泡的钨晶体的拉伸性能。应用共近邻分析法和位错分析法分析了晶体屈服前的微观结构演化机理。结果表明:当晶界上无He泡或只含有小尺寸单He泡时,在拉伸屈服前都经历了弹性阶段和结构相变阶段;在结构相变阶段,晶格原子的相对位置发生了变化。拉伸过程中,小He泡造成的晶格损伤会自动恢复,对晶体屈服应力和屈服应变无显著影响,He泡的能量受周围晶格钨原子间距的影响。晶界上的大尺寸He泡造成晶格损伤无法恢复,并且He泡越大,晶格损伤越大,相应地屈服应变 ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.
